The use of videotaped information in cancer genetic counselling: a randomized evaluation study

Evaluating genetic counseling session duration: A scoping review of patient care time, influencing factors, and impact on patient outcomes

One key element of evaluating the quality of a genetic counseling session is the measurement of its efficiency, yet limited research exists on how the genetic counseling process relates to time and which elements contribute to improved quality of care. A scoping review was undertaken to document studies that have reported genetic counseling patient care time and provide a landscape of the average patient care time, which factors impact patient care time, and how patient care time relates to experiences and outcomes. Twenty-five studies met criteria and were included. Patient care time was reported variably among the studies included. On average, genetic counseling patient care time was a mean of 60 min (53 min median) for observational studies and control groups in experimental studies and 44 min (41 min median) for intervention groups in experimental studies. Interventions impacting patient care time included pre-genetic counseling education and group genetic counseling sessions. The impact of patient care time on patient experiences and outcomes was rarely evaluated, and therefore, efficiency could not often be assessed in the studies. Studies that reported on patient care time and outcomes were able to draw conclusions such as shorter time did not negatively impact patients and some groups of patients may benefit from longer sessions. Most studies did not analyze the relationship between patient care time and patient experiences or outcomes. Future research should aim to identify factors influencing patient care time, assess the content of genetic counseling sessions, and evaluate patient care time in relation to patient experiences and outcomes. Understanding these aspects could lead to improved efficiency and patient-centered, equitable care in genetic counseling practices.

Interests and Experiences of Young Adults with Muscular Dystrophy in Receiving Genetic Information

Growing public awareness of genetic research, increased availability of genetic testing options, and the recent arrival of several gene-targeted therapies have combined to make genetic testing a topic of interest within many disease communities, including muscular dystrophies. We sought to investigate the genetic information received, the genetic services provided, the genetic information and services of interest to young adults with muscular dystrophy, and to identify existing gaps in the delivery of genetic information and services. Young adults with muscular dystrophy were surveyed about their interests and experiences in receiving genetic information/testing. Surveys were completed by 226 young adults with muscular dystrophy (150 male, 72 female; mean age = 21.6 years, range = 16-25 years) from Canada and the United States. Approximately 60% or less of respondents felt knowledgeable about genetic topics, including inheritance and reproductive options. Only 28% of respondents had previously met with a genetic counselor and 60% of respondents wanted to obtain more information. Findings highlight gaps between the receipt of and interest in genetic information.

Interventions to support decision making in people considering germline genetic testing for BRCA 1/2 pathogenic and likely pathogenic variants: A scoping review

Pathogenic and likely pathogenic variants in BRCA1 and BRCA2 (BRCA1/2) are medically actionable and may inform hereditary breast and ovarian cancer (HBOC) treatment and prevention. However, rates of germline genetic testing (GT) in people with and without cancer are suboptimal. Individuals' knowledge, attitudes, and beliefs may influence GT decisions. While genetic counseling (GC) provides decision support, the supply of genetic counselors is insufficient to meet demand. Accordingly, there is a need to explore the evidence on interventions that aim to support BRCA1/2 testing decisions. We conducted a scoping review of PubMed, CINAHL, Web of Science, and PsycINFO using search terms related to HBOC, GT, and decision making. First, we screened records to identify peer-reviewed reports that described interventions to support BRCA1/2 testing decisions. Next, we reviewed full-text reports and excluded studies that lacked statistical comparisons or enrolled previously tested individuals. Finally, we extracted study characteristics and findings into a table. All records and reports were reviewed independently by two authors; decisions were tracked in Rayyan, and discrepancies were resolved through discussion. Of 2116 unique citations, 25 met the eligibility criteria. Articles were published between 1997 and 2021 and described randomized trials and nonrandomized, quasi-experimental studies. Most studies tested technology-based (12/25, 48%) or written (9/25, 36%) interventions. Nearly half (12/25, 48%) of interventions were designed to complement traditional GC. Of the interventions compared to GC, 75% (6/8) increased or had a noninferior effect on knowledge, and 67% (4/6) decreased or had a noninferior effect on decisional conflict. Intervention effects on GT uptake were mixed, which may reflect evolving eligibility criteria for GT. Our findings suggest novel interventions may promote informed GT decision making, but many were developed to complement traditional GC. Trials that assess the effects of decision support interventions in diverse samples and evaluate implementation strategies for efficacious interventions are warranted.

Genetic counseling and testing for females at elevated risk for breast cancer: Protocol for the randomized controlled trial of the Know Your Risk intervention

BACKGROUND

Genetic counseling and testing have an important role in the care of patients at elevated risk for breast cancer. However, conventional pre- and post-test genetic counseling is labor and time intensive, less accessible for patients living outside major urban centers, and impractical on a large scale. A patient-driven approach to genetic counseling and testing may increase access, improve patients' experiences, affect efficiency of clinical practice, and help meet workforce demand. The objective of this 2-arm randomized controlled trial is to determine the efficacy of Know Your Risk (KYR), a genetic counseling patient preference intervention.

METHODS

Females (n = 1000) at elevated risk (>20% lifetime) for breast cancer will be randomized to the KYR intervention or conventional genetic counseling. The study will provide comprehensive assessment of breast cancer risk by multigene panel testing and validated polygenic risk score. Primary outcome is adherence to National Comprehensive Cancer Network guidelines for a clinical encounter every 6-12 months and an annual mammogram (breast MRI if recommended) determined by medical record review. Secondary outcomes include adherence to other recommended cancer screening tests determined by medical record review and changes in breast cancer knowledge, perception of risk, post-test/counseling distress, and satisfaction with counseling by completion of three surveys during the study. Study aims will be evaluated for non-inferiority of the KYR intervention compared to conventional genetic counseling.

CONCLUSION

If efficacious, the KYR intervention has the potential to improve patients' experience and may change how genetic counseling is delivered, inform best practices, and reduce workforce burden.

Randomized Controlled Trial of Patient Education Tools for Patients With Rheumatoid Arthritis

OBJECTIVE

The present study was undertaken to evaluate the efficacy of 2 educational tools for patients with rheumatoid arthritis (RA) by comparing a newly developed video tool, including storylines and testimonials, combined with a written booklet to the same written booklet alone.

METHODS

We conducted a randomized controlled trial. Our primary outcome was disease knowledge. Secondary outcomes were decisional conflict, self-efficacy, effective health care management, and satisfaction. Outcomes were measured before and after reviewing the materials, and 3 and 6 months later. Linear mixed-effects models were performed to evaluate changes over time.

RESULTS

In total, 221 participants received an educational video and booklet (n = 111) or a booklet alone (n = 110). The mean age was 50.8 years, mean disease duration was 4.8 years, 85% were female, and 24% had limited health literacy levels. Within groups, most outcomes improved between baseline and follow-up, but there were no statistically significant differences across groups. Patients receiving the video and booklet were more likely than those receiving the booklet alone to rate the presentation as excellent for providing information about the impact of RA, medication options, evidence about medications, benefits of medication, and self-care options. Factors significantly associated with greater improvements in knowledge and decisional conflict from baseline to 6 months included limited health literacy, lower educational level, and shorter disease duration.

CONCLUSION

Regardless of the delivery method, outcomes were improved up to 6 months after educational materials were delivered. Our findings support the implementation of self-administered educational materials in clinical settings, as they can result in sustained improvements in disease knowledge and decisional conflict.

The use of video for patient information and education: A scoping review of the variability and effectiveness of interventions

OBJECTIVE

To provide an overview of video interventions used for patient information and education, and of the tools used to evaluate their effectiveness, in order to consider the feasibility of developing generic guidelines and appraisal tools for the use of video in patient care.

METHODS

A scoping review was carried out to describe and synthesise emerging knowledge, using thematic analysis of data. Studies focussed upon videos for health professional education were excluded, as were those which consider the impact of videos available via social media.

RESULTS

A narrative overview of 65 identified papers provides insight into the range and scope of studies. Common themes emerge, notably the aim of reducing anxiety and the variety of instruments designed to measure this. The use of self-report questionnaires was common, but their design is variable.

CONCLUSION

Targeted video-based intervention can improve patient experience and outcomes. High utility guidelines and appraisal tools, transferable between contexts, are needed to facilitate deployments at scale for sustainable outcomes.

PRACTICE IMPLICATIONS

Video production guidelines and appraisal tools will be of value to those engaged in video development and deployment. Guidance should be based upon emerging evidence of effectiveness and incorporate an emphasis on reusability.

The role of the genetic testing industry in patient education of hereditary cancer: An observational study assessing the quality of patient education videos

OBJECTIVES

Genetic testing (GT) companies have developed patient education videos to supplement or replace pre-test genetic counseling (GC) by certified genetic counselors (CGC). The aim of this study was to assess the quality of these videos compared to the standard of care (SOC).

METHODS

Videos from four major GT companies were selected from an internet search identifying pre-test patient education videos. A scoring rubric with 22 questions and 36 total points was devised to assess quality metrics, as described by the National Cancer Institute and National Society of Genetic Counselors. Twenty-two individuals with varying genetics expertise (3 gynecologic oncologists, 3 academic generalists, 4 CGC, a genetics community health worker, 3 cancer care navigators, and 8 medical students) scored each video. Scorers were blinded to others' assessments.

RESULTS

Invitae had the highest median score (26/36), followed by Myriad (22/36), Ambry (17.5/36), and Color (15/36). All videos scored highly in explaining DNA basics, cancer development, and hereditary cancer predisposition. All addressed benefits of GT but failed to address potential disadvantages. All scored poorly in explaining medical terms and different GT options. There was variability in addressing patient concerns including cost, privacy, and procedure.

CONCLUSIONS

There is significant variation in the content of pre-test patient education videos between GT companies. None of the videos met the SOC for pre-test GC, and none addressed disadvantages of GT, possibly due to a conflict of interest. With improvement in content, accessibility, and use of interactive platforms, these videos may serve as an adjunct to in-person pre-test GC.

Impact of patient education videos on genetic counseling outcomes after exome sequencing

OBJECTIVE

Growing use of clinical exome sequencing (CES) has led to an increased burden of genomic education. Self-guided educational tools can minimize the educational burden for genetic counselors (GCs). The effectiveness of these tools must be evaluated.

METHODS

Parents of patients offered CES were randomized to watch educational videos before their visit or to receive routine care. Parents and GCs were surveyed about their experiences following the sessions. The responses of the video (n = 102) and no-video (n = 105) groups were compared.

RESULTS

GCs reported no significant differences between parents in the video and no-video groups on genetics knowledge or CES knowledge. In contrast, parents' scores on genetics knowledge questions were lower in the video than no-video group (p = 0.007). Most parents reported the videos were informative, and the groups did not differ in satisfaction with GCs or decisions to have CES.

CONCLUSION

GCs and parents perceived the videos to be beneficial. However, lower scores on genetics knowledge questions highlight the need for careful development of educational tools.

PRACTICE IMPLICATIONS

Educational tools should be developed and assessed for effectiveness with the input of all stakeholders before widespread implementation. Better measures of the effectiveness of these educational tools are needed.

Risk Assessment, Genetic Counseling, and Genetic Testing for BRCA-Related Cancer: US Preventive Services Task Force Recommendation Statement

IMPORTANCE

Potentially harmful mutations of the breast cancer susceptibility 1 and 2 genes (BRCA1/2) are associated with increased risk for breast, ovarian, fallopian tube, and peritoneal cancer. For women in the United States, breast cancer is the most common cancer after nonmelanoma skin cancer and the second leading cause of cancer death. In the general population, BRCA1/2 mutations occur in an estimated 1 in 300 to 500 women and account for 5% to 10% of breast cancer cases and 15% of ovarian cancer cases.

OBJECTIVE

To update the 2013 US Preventive Services Task Force (USPSTF) recommendation on risk assessment, genetic counseling, and genetic testing for BRCA-related cancer.

EVIDENCE REVIEW

The USPSTF reviewed the evidence on risk assessment, genetic counseling, and genetic testing for potentially harmful BRCA1/2 mutations in asymptomatic women who have never been diagnosed with BRCA-related cancer, as well as those with a previous diagnosis of breast, ovarian, tubal, or peritoneal cancer who have completed treatment and are considered cancer free. In addition, the USPSTF reviewed interventions to reduce the risk for breast, ovarian, tubal, or peritoneal cancer in women with potentially harmful BRCA1/2 mutations, including intensive cancer screening, medications, and risk-reducing surgery.

FINDINGS

For women whose family or personal history is associated with an increased risk for harmful mutations in the BRCA1/2 genes, or who have an ancestry associated with BRCA1/2 gene mutations, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are moderate. For women whose personal or family history or ancestry is not associated with an increased risk for harmful mutations in the BRCA1/2 genes, there is adequate evidence that the benefits of risk assessment, genetic counseling, genetic testing, and interventions are small to none. Regardless of family or personal history, the USPSTF found adequate evidence that the overall harms of risk assessment, genetic counseling, genetic testing, and interventions are small to moderate.

CONCLUSIONS AND RECOMMENDATION

The USPSTF recommends that primary care clinicians assess women with a personal or family history of breast, ovarian, tubal, or peritoneal cancer or who have an ancestry associated with BRCA1/2 gene mutations with an appropriate brief familial risk assessment tool. Women with a positive result on the risk assessment tool should receive genetic counseling and, if indicated after counseling, genetic testing. (B recommendation) The USPSTF recommends against routine risk assessment, genetic counseling, or genetic testing for women whose personal or family history or ancestry is not associated with potentially harmful BRCA1/2 gene mutations. (D recommendation).

Risk Assessment, Genetic Counseling, and Genetic Testing for BRCA-Related Cancer in Women: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Pathogenic mutations in breast cancer susceptibility genes BRCA1 and BRCA2 increase risks for breast, ovarian, fallopian tube, and peritoneal cancer in women; interventions reduce risk in mutation carriers.

OBJECTIVE

To update the 2013 US Preventive Services Task Force review on benefits and harms of risk assessment, genetic counseling, and genetic testing for BRCA1/2-related cancer in women.

DATA SOURCES

Cochrane libraries; MEDLINE, PsycINFO, EMBASE (January 1, 2013, to March 6, 2019, for updates; January 1, 1994, to March 6, 2019, for new key questions and populations); reference lists.

STUDY SELECTION

Discriminatory accuracy studies, randomized clinical trials (RCTs), and observational studies of women without recently diagnosed BRCA1/2-related cancer.

DATA EXTRACTION AND SYNTHESIS

Data on study methods, setting, population characteristics, eligibility criteria, interventions, numbers enrolled and lost to follow-up, outcome ascertainment, and results were abstracted. Two reviewers independently assessed study quality.

MAIN OUTCOMES AND MEASURES

Cancer incidence and mortality; discriminatory accuracy of risk assessment tools for BRCA1/2 mutations; benefits and harms of risk assessment, genetic counseling, genetic testing, and risk-reducing interventions.

RESULTS

For this review, 103 studies (110 articles; N = 92 712) were included. No studies evaluated the effectiveness of risk assessment, genetic counseling, and genetic testing in reducing incidence and mortality of BRCA1/2-related cancer. Fourteen studies (n = 43 813) of 8 risk assessment tools to guide referrals to genetic counseling demonstrated moderate to high accuracy (area under the receiver operating characteristic curve, 0.68-0.96). Twenty-eight studies (n = 8060) indicated that genetic counseling was associated with reduced breast cancer worry, anxiety, and depression; increased understanding of risk; and decreased intention for testing. Twenty studies (n = 4322) showed that breast cancer worry and anxiety were higher after testing for women with positive results and lower for others; understanding of risk was higher after testing. In 8 RCTs (n = 54 651), tamoxifen (relative risk [RR], 0.69 [95% CI, 0.59-0.84]; 4 trials), raloxifene (RR, 0.44 [95% CI, 0.24-0.80]; 2 trials), and aromatase inhibitors (RR, 0.45 [95% CI, 0.26-0.70]; 2 trials) were associated with lower risks of invasive breast cancer compared with placebo; results were not specific to mutation carriers. Mastectomy was associated with 90% to 100% reduction in breast cancer incidence (6 studies; n = 2546) and 81% to 100% reduction in breast cancer mortality (1 study; n = 639); oophorectomy was associated with 69% to 100% reduction in ovarian cancer (2 studies; n = 2108); complications were common with mastectomy.

CONCLUSIONS AND RELEVANCE

Among women without recently diagnosed BRCA1/2-related cancer, the benefits and harms of risk assessment, genetic counseling, and genetic testing to reduce cancer incidence and mortality have not been directly evaluated by current research.

Development and Preliminary Evaluation of IRD-1-2-3: An Animated Video to Inform Transplant Candidates About Increased Risk Donor Kidneys

BACKGROUND

Current educational interventions about increased risk donors (IRDs) are less effective in improving knowledge among African American (AA) kidney transplant candidates compared to other races. We aimed to develop an IRD educational animated video culturally responsive to AAs and conduct feasibility testing.

METHODS

Between May 1, 2018, and June 25, 2018, we iteratively refined a culturally targeted video for AAs with input from multiple stakeholders. We then conducted a one group pre-post study between June 28, 2018, and October 29, 2018, with 40 kidney transplant candidates to assess the feasibility and acceptability of the video to improve participant knowledge and obtain feedback about IRD understanding, self-efficacy, and willingness. A mixed population was chosen to obtain race-specific acceptability data and efficacy estimates to inform a larger study.

RESULTS

Three themes emerged and informed video development; misattribution of IRD to kidney quality, IRD terminology as a barrier to meaningful understanding, and variable reactions to a 1:1000 risk estimate. The study cohort was 50% AA. Median IRD knowledge increased from 5 to 7.5 (P = 0.001) overall and from 5 to 7 (P < 0.001) among AAs. The frequency of positive responses increased pre-post video for understanding of (23% vs 83%, P < 0.001), self-efficacy to decide about (38% vs 70%, P < 0.001), and willingness to accept IRD kidneys (25% vs 72%, P < 0.001). Over 90% of participants provided positive ratings on each of the 6 acceptability items.

CONCLUSIONS

A culturally responsive IRD educational video was developed in collaboration with key stakeholders. Quantitative results indicate the video was acceptable and promising to impact IRD knowledge among AA and non-AA kidney transplant candidates.

Investigating barriers to genetic counseling and germline mutation testing in women with suspected hereditary breast and ovarian cancer syndrome and Lynch syndrome

OBJECTIVE

The aim of the current study was to explore barriers to genetic counseling and testing in women with gynecological cancers deemed at significant risk of carrying a germline mutation.

METHODS

A qualitative study using semi-structured interviews and inductively analysed thematically. Eight patients with ovarian or endometrial cancer participated in individual semi-structured telephone interviews that assessed motivation for genetic counseling and testing, perceived benefits and barriers, timing of the approach, perceptions of the referral process to genetic services and locus of control in relation to cancer and health.

RESULTS

Analysis of the interview transcripts revealed five themes relating to perceptions of genetic counseling and testing: Lack of importance; Level of information received; Timing of referral processes; Fear and anxiety; Resistance to and perceptions of counseling.

CONCLUSIONS

Participants had a limited understanding of hereditary cancer syndromes and did not appreciate the benefits of genetic testing. A consistent approach at the time of referral to genetic services is needed to ensure that the level and format of information is appropriate for patients.

PRACTICE IMPLICATIONS

The rationale for genetic testing needs to be better explained to patients and the timing of referral should be based both on treatment priorities and patient preferences.

Increasing confidence and changing behaviors in primary care providers engaged in genetic counselling

BACKGROUND

Screening and counseling for genetic conditions is an increasingly important part of primary care practice, particularly given the paucity of genetic counselors in the United States. However, primary care physicians (PCPs) often have an inadequate understanding of evidence-based screening; communication approaches that encourage shared decision-making; ethical, legal, and social implication (ELSI) issues related to screening for genetic mutations; and the basics of clinical genetics. This study explored whether an interactive, web-based genetics curriculum directed at PCPs in non-academic primary care settings was superior at changing practice knowledge, attitudes, and behaviors when compared to a traditional educational approach, particularly when discussing common genetic conditions.

METHODS

One hundred twenty one PCPs in California and Pennsylvania physician practices were randomized to either an Intervention Group (IG) or Control Group (CG). IG physicians completed a 6 h interactive web-based curriculum covering communication skills, basics of genetic testing, risk assessment, ELSI issues and practice behaviors. CG physicians were provided with a traditional approach to Continuing Medical Education (CME) (clinical review articles) offering equivalent information.

RESULTS

PCPs in the Intervention Group showed greater increases in knowledge compared to the Control Group. Intervention PCPs were also more satisfied with the educational materials, and more confident in their genetics knowledge and skills compared to those receiving traditional CME materials. Intervention PCPs felt that the web-based curriculum covered medical management, genetics, and ELSI issues significantly better than did the Control Group, and in comparison with traditional curricula. The Intervention Group felt the online tools offered several advantages, and engaged in better shared decision making with standardized patients, however, there was no difference in behavior change between groups with regard to increases in ELSI discussions between PCPs and patients.

CONCLUSION

While our intervention was deemed more enjoyable, demonstrated significant factual learning and retention, and increased shared decision making practices, there were few differences in behavior changes around ELSI discussions. Unfortunately, barriers to implementing behavior change in clinical genetics is not unique to our intervention. Perhaps the missing element is that busy physicians need systems-level support to engage in meaningful discussions around genetics issues. The next step in promoting active engagement between doctors and patients may be to put into place the tools needed for PCPs to easily access the materials they need at the point-of-care to engage in joint discussions around clinical genetics.

Impact of a randomized controlled educational trial to improve physician practice behaviors around screening for inherited breast cancer

BACKGROUND

Many primary care physicians (PCPs) are ill-equipped to provide screening and counseling for inherited breast cancer.

OBJECTIVE

To evaluate the outcomes of an interactive web-based genetics curriculum versus text curriculum for primary care physicians.

DESIGN

Randomized two-group design.

PARTICIPANTS

121 California and Pennsylvania community physicians.

INTERVENTION

Web-based interactive genetics curriculum, evaluated against a control group of physicians who studied genetics review articles. After education, physicians interacted with an announced standardized patient (SP) at risk for inherited breast cancer.

MAIN MEASURES

Transcripts of visit discussions were coded for presence or absence of 69 topics relevant to inherited breast cancer.

KEY RESULTS

Across all physicians, history-taking, discussions of test result implications, and exploration of ethical and legal issues were incomplete. Approximately half of physicians offered a genetic counseling referral (54.6%), and fewer (43.8%) recommended testing. Intervention physicians were more likely than controls to explore genetic counseling benefits (78.3% versus 60.7%, P = 0.048), encourage genetic counseling before testing (38.3% versus 21.3%, P = 0.048), ask about a family history of prostate cancer (25.0% versus 6.6%, P = 0.006), and report that a positive result indicated an increased risk of prostate cancer for male relatives (20.0% versus 1.6%, P = 0.001). Intervention-group physicians were less likely than controls to ask about Ashkenazi heritage (13.3% versus 34.4%, P = 0.01) or to reply that they would get tested when asked, "What would you do?" (33.3% versus 54.1%, P = 0.03).

CONCLUSIONS

Physicians infrequently performed key counseling behaviors, and this was true regardless of whether they had completed the web-based interactive training or read clinical reviews.

Factors affecting recall of different types of personal genetic information about Alzheimer's disease risk: the REVEAL study

METHODS

Data were obtained through a multisite clinical trial in which different types of genetic risk-related information were disclosed to individuals (n = 246) seeking a risk assessment for Alzheimer's disease.

RESULTS

Six weeks after disclosure, 83% of participants correctly recalled the number of risk-increasing APOE alleles they possessed, and 74% correctly recalled their APOE genotype. While 84% of participants recalled their lifetime risk estimate to within 5 percentage points, only 51% correctly recalled their lifetime risk estimate exactly. Correct recall of the number of APOE risk-increasing alleles was independently associated with higher education (p < 0.001), greater numeracy (p < 0.05) and stronger family history of Alzheimer's disease (p < 0.05). Before adjustments for confounding, correct recall of APOE genotype was also associated with higher education, greater numeracy and stronger family history of Alzheimer's disease, as well as with higher comfort with numbers and European American ethnicity (all p < 0.05). Correct recall of the lifetime risk estimate was independently associated only with younger age (p < 0.05).

CONCLUSIONS

Recall of genotype-specific information is high, but recall of exact risk estimates is lower. Incorrect recall of numeric risk may lead to distortions in understanding risk. Further research is needed to determine how best to communicate different types of genetic risk information to patients, particularly to those with lower educational levels and lower numeracy. Health-care professionals should be aware that each type of genetic risk information may be differentially interpreted and retained by patients and that some patient subgroups may have more problems with recall than others.

Follow-up effects of a tailored pre-counseling website with question prompt in breast cancer genetic counseling

OBJECTIVE

Pre-counseling education helps counselees to prepare for breast cancer genetic counseling and might subsequently result in more positive experiences, improved cognitive outcomes and more experienced control. This study assessed the effects of a website with tailored information and a blank sheet to fill in questions (question prompt; QP), at 1 week and 1 year post-counseling.

METHODS

Consecutive counselees were randomized to the usual care group (UC) or the intervention group (UC+website+QP). Counselees completed questionnaires pre- and post-counseling and 1 year follow-up. We conducted multilevel regression analyses corrected for time.

RESULTS

Intervention group counselees (n = 103) were more satisfied about their final visit (β = .35; CI: .06-.65; P = .02; n = 156) than UC group counselees (n = 94). Intervention group counselees also reported more positive experiences with the counseling (β = .32; CI: .06-.59; P = .02; n = 188) and higher perceived personal control 1 year post-counseling (β = .51; CI: .18-.84; P = .002; n = 193). No significant effects were found on recall, knowledge, anxiety, cancer worry, risk perception alignment and adherence to breast surveillance advice.

CONCLUSION

This study shows that pre-counseling education providing tailored information and QP, might lead to improvements in experiences with the counseling and perceived personal control 1 year post-counseling.

PRACTICE IMPLICATIONS

Online pre-visit information is a feasible tool to enhance counselees' experiences.

Interactive e-counselling for genetics pre-test decisions: where are we now?

In-person genetic counselling (GC) is the model typically used to provide patients with information regarding their genetic testing options. Current and emerging demand for genetic testing may overburden the health care system and exceed the available numbers of genetic counsellors. Furthermore, GC is not always available at times and places convenient for patients. There is little evidence that the in-person model alone is always optimal and alternatives to in-person GC have been studied in genetics and other areas of health care. This review summarizes the published evidence between 1994 and March 2014 for interactive e-learning and decisional support e-tools that could be used in pre-test GC. A total of 21 papers from 15 heterogeneous studies of interactive e-learning tools, with or without decision aids, were reviewed. Study populations, designs, and outcomes varied widely but most used an e-tool as an adjunct to conventional GC. Knowledge acquisition and decisional comfort were achieved and the e-tools were generally well-accepted by users. In a time when health care budgets are constrained and availability of GC is limited, research is needed to determine the specific circumstances in which e-tools might replace or supplement some of the functions of genetic counsellors.

Women's preferences for selective estrogen reuptake modulators: an investigation using protection motivation theory

OBJECTIVE

Selective estrogen receptor modulators (SERMs) reduce breast cancer risk by 38%. However, uptake is low and the reasons are not well understood. This study applied protection motivation theory (PMT) to determine factors associated with intention to take SERMs.

METHODS

Women at increased risk of breast cancer (N=107), recruited from two familial cancer clinics in Australia, completed a questionnaire containing measures of PMT constructs. Hierarchical multiple linear regression analysis was used to analyze the data.

RESULTS

Forty-five percent of women said they would be likely or very likely to take SERMs in the future. PMT components accounted for 40% of variance in intention to take SERMs. Perceived vulnerability, severity and response efficacy appeared the most influential in women's decisions to take or not take SERMs.

CONCLUSION

Many women are interested in SERMs as a risk management option. Accurate risk estimation and an understanding of the benefits of SERMs are critical to women's decision making.

PRACTICE IMPLICATIONS

Health professionals need to explore women's perceptions of their risk and its consequences, as well as providing clear evidence-based information about the efficacy of SERMs. Exploring the source and strength of beliefs about SERMs may allow more effective, tailored counseling.

Women's preferences for selective estrogen reuptake modulators: an investigation using the time trade-off technique

Purpose

Selective Estrogen Receptor Modulators (SERMs) reduce the risk of breast cancer for women at increased risk by 38%. However, uptake is extremely low and the reasons for this are not completely understood. The aims of this study were to utilize time trade-off methods to determine the degree of risk reduction required to make taking SERMs worthwhile to women, and the factors associated with requiring greater risk reduction to take SERMs.

Methods

Women at increased risk of breast cancer (N = 107) were recruited from two familial cancer clinics in Australia. Participants completed a questionnaire either online or in pen and paper format. Hierarchical multiple linear regression analysis was used to analyze the data.

Results

Overall, there was considerable heterogeneity in the degree of risk reduction required to make taking SERMs worthwhile. Women with higher perceived breast cancer risk and those with stronger intentions to undergo (or who had undergone) an oophorectomy required a smaller degree of risk reduction to consider taking SERMs worthwhile.

Conclusion

Women at increased familial risk appear motivated to consider SERMs for prevention. A tailored approach to communicating about medical prevention is essential. Health professionals could usefully highlight the absolute (rather than relative) probability of side effects and take into account an individual’s perceived (rather than objective) risk of breast cancer.

Improving subjective perception of personal cancer risk: systematic review and meta-analysis of educational interventions for people with cancer or at high risk of cancer

BACKGROUND

Newly diagnosed patients with cancer require education about the disease, the available treatments and potential consequences of treatment. Greater understanding of cancer risk has been found to be associated with greater health-related quality of life, improved psychological adjustment and greater health-related behaviours. The aim of this sytematic review was to assess the effectiveness of educational interventions in improving subjective cancer risk perception and to appraise the quality of the studies.

METHODS

We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs) and prospective observational studies. Eligible studies were identified via Medline, PsycINFO, AMED, CINAHL and Embase databases. After screening titles and abstracts, two reviewers independently assessed the eligibility of 206 full-text articles.

RESULTS

Forty papers were included in the review; the majority of studies were conducted among breast cancer patients (n = 29) and evaluated the effect of genetic counselling on personal perceived risk (n = 25). Pooled results from RCTs (n = 12) showed that, both in the short and long term, educational interventions did not significantly influence risk perception level (standardised mean difference 0.05, 95% CI -0.24-0.34; p = 0.74) or accuracy (odds ratio = 1.96, 95% CI: 0.61-6.25; p = 0.26). Only one RCT reported a short-term difference in risk ratings (p = 0.01). Of prospective observational studies (n = 28), many did demonstrate changes in the level of perceived risk and improved risk accuracy and risk ratings in both the short and long term. However, only one (of three) observational studies reported a short-term difference in risk ratings (p < = 0.003).

CONCLUSION

Further development and investigation of educational interventions using good quality, RCTs are warranted.

Feasibility trial of a Spanish-language multimedia educational intervention

BACKGROUND

Hispanic cancer patients are underrepresented in clinical trials; research suggests lack of knowledge and language barriers contribute to low accrual. Multimedia materials offer advantages to Hispanic populations because they have high acceptability, are easy to disseminate, and can be viewed with family.

PURPOSE

Hispanic cancer patients and caregivers participated in focus groups to aid in developing a Spanish-language multimedia intervention to educate Hispanic cancer patients about clinical trials. We explored the feasibility of delivering the intervention in medical oncology clinics.

METHODS

A total of 35 patients were randomized to either the multimedia intervention group (n = 18) or a control group (n = 17) who were asked to read the National Cancer Institute's Spanish-language clinical trials brochure. Self-reported data on knowledge about and attitudes toward clinical trials, self-efficacy for participating in a clinical trial, intention to participate in a clinical trial if asked, and receptivity to information about a clinical trial were collected at baseline and 10 days later.

RESULTS

Delivery of the multimedia presentation in oncology clinics was feasible. The intervention group had more knowledge about clinical trials at follow-up than the control group; scores for intention to participate in a clinical trial by participants in the intervention group increased from 3.8 to 4.0 of a possible 5, but declined in the control group from 4.5 to 4.1. No statistically significant difference was detected between groups in scores for attitudes or self-efficacy for making a decision to participate in a clinical trial.

LIMITATIONS

Our sample size was inadequate to identify differences between the informational methods. Although all patients were asked about their willingness to participate in a clinical trial, this decision was hypothetical. In addition, the study was conducted with a sample of Spanish-speaking Hispanic cancer patients at a comprehensive cancer center in Florida. Thus, the results may not generalize to other Hispanic populations.

CONCLUSION

In the pilot project, we demonstrated the feasibility of delivering multimedia information to patients in medical oncology clinics. Because delivery in a clinical setting was found to be feasible, a larger study should be conducted to evaluate the efficacy of the multimedia intervention with respect to promoting accrual of Hispanic patients to clinical trials.

Improving awareness of cancer clinical trials among Hispanic patients and families: audience segmentation decisions for a media intervention

Clinical trials hold great promise for cancer treatment; yet, Hispanic cancer patients have low rates of clinical trial participation. Lack of awareness and knowledge of clinical trials and language barriers may account for low participation rates. Patient education through audiovisual materials can improve knowledge of and attitudes toward clinical trials among Hispanic populations. In this study, 36 Hispanic cancer patients/survivors and caregivers in Florida and Puerto Rico participated in focus groups to aid in developing a Spanish-language DVD and booklet intervention designed to increase knowledge about clinical trials. Focus group results showed (a) low levels of knowledge about clinical trials, (b) uncertainty about why a physician would expect a patient to make a choice about treatment, and (c) desire for family participation in decision making. Respondents expressed various preferences for aspects of the DVD such as showing extended family in the DVD and physician explanations about key terms. On the basis of these preferences, the authors developed a creative brief for a DVD. The content of the DVD was reviewed by Hispanic community leaders and key stakeholders. A final DVD was created, in Spanish, using Hispanic patients and physicians, which contained the information deemed important from the focus groups and stakeholder interviews. The DVD is complete with companion booklet and currently undergoing a randomized control trial.

Effectiveness of a condensed protocol for disclosing APOE genotype and providing risk education for Alzheimer disease

PURPOSE

Brief, effective models of patient genetic education are needed for common, complex diseases. Using Alzheimer disease as a model, we compared participants' risk knowledge and recall in extended versus condensed education protocols.

METHODS

A four-site randomized clinical trial enrolled 280 first-degree relatives of individuals with Alzheimer disease (mean age = 58 years, 71% female); each received lifetime Alzheimer disease risk information (range: 13-74%) that incorporated apolipoprotein E genotype. In the condensed protocol, participants received an educational brochure in place of an in-person education session. Outcomes were assessed at 6 weeks and 6 months following risk disclosure.

RESULTS

The condensed protocol required less clinician time than the extended protocol (mean = 34 min vs. 77 min). The groups did not differ on recall of apolipoprotein E genotype or lifetime risk, and most participants in both groups recalled and retained this information over time. Both groups showed improvement from baseline in Alzheimer disease risk knowledge (e.g., understanding the magnitude of apolipoprotein E genotype effect on risk).

CONCLUSION

A condensed protocol for communicating genetic risk for Alzheimer disease achieved similar educational results as an extended protocol in this study. Further research should explore the efficacy of brief genetic education protocols for complex diseases in diverse populations.

Development of a cancer clinical trials multi-media intervention: clinical trials: are they right for you?

OBJECTIVE

To describe processes used to develop a multi-media psycho-educational intervention to prepare patients for a discussion about cancer clinical trials (CTs).

METHODS

Guided by a Steering Committee, formative research was conducted to develop an informative and engaging tool about cancer CTs. Twenty-three patients and caregivers participated in formative in-depth interviews to elicit information about perceptions of cancer CTs to inform production of a new media product.

RESULTS

Formative research revealed participants had concerns about experimentation, held beliefs that cancer CTs were for patients who had no other treatment options, and wanted a balance of information about pros and cons of CT participation. The value of physicians as credible spokespersons and the use of patients as role-models were supported. Using iterative processes, the production team infused the results into creation of a multimedia psycho-educational intervention titled Clinical Trials: Are they Right for You?

CONCLUSION

An intervention, developed through an iterative consumer-focused process involving multiple stakeholders and formative research, may result in an engaging informative product.

PRACTICE IMPLICATIONS

If found to be efficacious, Clinical Trials: Are they Right for You? is a low-cost and easily disseminated multimedia psycho-educational intervention to assist cancer patients with making an informed decision about cancer CTs.

A pre-visit tailored website enhances counselees' realistic expectations and knowledge and fulfils information needs for breast cancer genetic counselling

Counselees who are the first in their family to request breast cancer genetic counselling often don't know what to expect or have unrealistic expectations of genetic counselling. Receiving tailored information might help them to prepare for their first visit. We conducted a study of the effects of a pre-visit website providing computer-tailored information (E-info gene(ca)), on counselees' expectations, knowledge about breast cancer and heredity and information needs. Counselees were randomized to receive usual care (UC) or UC plus website. All counselees completed a baseline questionnaire and those randomized to the intervention group also completed a questionnaire after having viewed the website. After having accessed E-info gene(ca) counselees (n = 101) better knew what to expect of their first visit (χ(2) = 4.43; P = .04) and less often showed unrealistic expectations about possibilities for DNA-testing (χ(2) = 4.84; P = .03) than counselees in the UC group (n = 89). In addition, the website increased counselees' knowledge of breast cancer and heredity (B = .23; P = .003) and lowered their information needs (B = -.16; P = .000) compared to the UC group. Especially, information concerning procedural aspects and emotional consequences of genetic counselling was considered less important. This study showed that counselees know more and need less when they are provided with extended pre-visit information through a tailored website and counselees enter the visit with more realistic expectations of genetic counselling. This might facilitate and focus communication within the subsequent consultation.

Informed consent and decision-making about adult-to-adult living donor liver transplantation: a systematic review of empirical research

Adult-to-adult living donor liver transplantation (LDLT) is a complex procedure that poses serious health risks to and provides no direct health benefit for the donor. Because of this uneven risk-benefit ratio, ensuring donor autonomy through informed consent is critical. To assess the current knowledge pertaining to informed consent for LDLT, we conducted a systematic review of the empirical literature on donors' decision-making process, comprehension about risks and outcomes, and information needs for LDLT. Of the 1423 identified articles, 24 met final review criteria, representing the perspective of approximately 2789 potential and actual donors. As donors' decisions to donate often occur before evaluation, they often make uninformed decisions. The review found that 88% to 95% of donors reported understanding information clinicians disclosed about risks and benefits. However, donors reported unmet information needs, knowledge gaps regarding risks, and unanticipated complications. Few donors reported feeling pressure to donate. Most studies were limited by cultural differences, small sample sizes, inconsistent measures, and poor methodological approaches. This systematic review suggests that informed consent for LDLT is sub-optimal as donors do not adequately appreciate disclosed information during the informed consent process, despite United Network for Organ Sharing/CMS regulations requiring formal psychological evaluation of donor candidates. Interventions are needed to improve donor-clinician communication during the LDLT informed consent process such as through the use of comprehension assessment tools and e-health educational tools that leverage adult learning theory to effectively convey LDLT outcome data.

Effects of a pre-visit educational website on information recall and needs fulfilment in breast cancer genetic counselling, a randomized controlled trial

Introduction

Pre-visit education which helps counselees to prepare for their first visit for breast cancer genetic counseling might enhance information recall and needs fulfilment. This study assessed the effects of a pre-visit website with tailored information and question prompt sheet (QPS), named E-info gene^ca.

Methods

A total of 197 counselees were randomized to receive usual care (UC) or UC plus E-info gene^ca. All counselees completed a pre- and post-visit questionnaire and visits were videotaped. We studied effects on counselees' information recall, knowledge about breast cancer and heredity, fulfillment of needs, risk perception alignment, anxiety and perceived personal control, using multilevel regression analyses.

Results

Intent-to-treat analysis showed that counselees in the intervention group (n = 103) had higher levels of recall of information from the consultation (β = .32; confidence interval (CI): .04 to .60; P = .02; d = .17) and post-visit knowledge of breast cancer and heredity (β = .30; CI: .03 to .57; P = .03) than counselees in the UC group (n = 94). Also, intervention group counselees reported better fulfilment of information needs (β = .31; CI: .03 to .60; P = .03). The effects of the intervention were strongest for those counselees who did not receive an indication for DNA testing. Their recall scores showed a larger increase (β = .95; CI: .32 to 1.59; P = .003; d = .30) and their anxiety levels dropped more in the intervention compared to the UC group (β = -.60; CI: -1.12 to -.09; P = .02). No intervention effects were found after the first visit on risk perception alignment or perceived personal control.

Conclusions

This study shows that pre-counseling education, using tailored information technology, leads to more effective first visits for breast cancer genetic counseling, in particular for counselees who received no indication for DNA testing and, therefore, had no indication for a second visit. Future study should focus on the effects of a pre-visit website on the outcomes after a complete series of visits.

Patient outcomes associated with group and individual genetic counseling formats

Identifying new methods to deliver cancer genetic counseling (GC) are needed to meet the growing interest in BRCA1/2 testing. The goal of this pilot feasibility study was designed to test the initial acceptability of group GC on selected patient outcomes (satisfaction, distress, perceived control) in a breast/ovarian cancer genetics clinic setting. Sixty-five participants at increased risk for hereditary breast/ovarian cancer (HBOC) agreed to participate in self-selected individual or group GC appointments. Forty-nine participants completed all study questionnaires and were included in the analyses. There were significant improvements for participants in both the individual and group GC formats with regard to perceived personal control, general psychological distress and cancer-specific psychological distress scores. Participants in both the individual and group formats reported high satisfaction scores on the Genetic Counseling Satisfaction Scale. Study results suggest that group GC may be feasible and acceptable to high-risk women.

Cancer genetic risk assessment for individuals at risk of familial breast cancer

BACKGROUND

The recognition of an inherited component to breast cancer has led to an increase in demand for information, reassurance, and genetic testing, which has resulted in the creation of genetic clinics for familial cancer. The first step for patients referred to a cancer genetic clinic is a risk assessment.

OBJECTIVES

To evaluate the impact of cancer genetic risk-assessment services on patients at risk of familial breast cancer.

SEARCH METHODS

The specialised register maintained by the Cochrane Breast Cancer Group was searched on 16th February 2005. We also searched MEDLINE, EMBASE, CINAHL, PsycLIT, CENTRAL, DARE, ASSIA, Web of Science, SIGLE and LILACS. The original searches covered the period 1985 to February 2005. We also handsearched relevant journals. For this review update the search was repeated through to April 2011.

SELECTION CRITERIA

We considered trials looking at interventions for cancer genetic risk-assessment services for familial breast cancer for inclusion. Trials assessed outcomes such as understanding of risk, satisfaction and psychological well-being. We excluded studies if they concerned cancers other than breast cancer or if participants were not at risk of inherited breast cancer. We also excluded trials concerning the provision of general cancer genetic information or education as this review was concerned with the delivery of genetic risk assessment. Participants could be individuals of any age or gender, with or without a known BRCA mutation, but without a previous history of breast cancer or any other serious illness.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Additional information was sought from investigators as necessary. Due to the heterogeneity of both the interventions and outcomes, we reported data descriptively.

MAIN RESULTS

In this review update, we included five new trials, bringing the total number of included studies to eight. The included trials (pertaining to 10 papers), provided data on 1973 participants and assessed the impact of cancer genetic risk assessment on outcomes including perceived risk of inherited cancer, and psychological distress. This review suggests that cancer genetic risk-assessment services help to reduce distress, improve the accuracy of the perceived risk of breast cancer, and increase knowledge about breast cancer and genetics. The health professional delivering the risk assessment does not appear to have a significant impact on these outcomes.

AUTHORS' CONCLUSIONS

This review found favourable outcomes for patients after risk assessment for familial breast cancer. However, there were too few papers to make any significant conclusions about how best to deliver cancer genetic risk-assessment services. Further research is needed assessing the best means of delivering cancer risk assessment, by different health professionals, in different ways and in alternative locations.

Longer-term influence of breast cancer genetic counseling on cognitions and distress: smaller benefits for affected versus unaffected women

OBJECTIVE

To evaluate outcomes of breast cancer genetic counseling in women with and without breast cancer.

METHODS

Seventy-seven first-time attendees (n=44 affected) completed questionnaires assessing cognitions (risk accuracy, knowledge, perceived personal control [PPC]) and distress (state anxiety [STAI], cancer-related stress reactions [IES]) from immediately before to immediately and six months after completing counseling. Data were analyzed using multilevel repeated measures and trend analyses.

RESULTS

In affected counselees, mean cognitions did not significantly differ over time, anxiety significantly decreased, and IES levels were increased immediately post-counseling. In unaffected counselees, cognitions significantly improved over time except for knowledge. Distress levels showed similar patterns as in affected women. Improvements in cognitions and distress were significantly smaller in affected versus unaffected women.

CONCLUSION

Overall, counseling educates women about breast cancer risk and alleviates their anxiety. Importantly, benefits gained at immediate follow-up seem maintained over time.

PRACTICE IMPLICATION

Affected women seem to benefit less from counseling. Counselors may need to devote more effort into educating these women and addressing their anxieties. Future studies should confirm the unexpected finding that cancer-related distress increased immediately post-counseling.

Distress and psychosocial needs of a heterogeneous high risk familial cancer population

In order to assess the levels of distress and psychosocial support needs of a high risk population, we undertook a study to look at both the objective and subjective levels of distress and the wants and needs of individuals from a high familial cancer risk population. Three hundred and eighteen individuals (160 affected, 158 unaffected) completed several distress and psychosocial needs questionnaires (including the Brief Symptom Inventory-18). Sixty key informants were also surveyed about their perspective on the support needs of this population. In the largely female (90%), largely HBOC syndrome group (approximately 90%), 20% had significant levels of generalized distress, with no significant differences between affected and unaffected individuals. Generalized distress was also not significantly different as a function of mutation status. Individuals who received inconclusive test results, however, were more likely to indicate somatic symptoms of distress. Those individuals who did not have social support were more likely to be those who had never had cancer and who either had a mutation, received inconclusive test results, or were not tested. Key informants were most likely to indicate that patients need more support. These results provide evidence for the importance of establishing regular psychosocial distress screening, including a focus on somatic symptoms, in such high risk populations.

Direct-to-consumer genetic testing: an assessment of genetic counselors' knowledge and beliefs

PURPOSE

Direct-to-consumer genetic testing is a new means of obtaining genetic testing outside of a traditional clinical setting. This study assesses genetic counselors' experience, knowledge, and beliefs regarding direct-to-consumer genetic testing for tests that would currently be offered in genetics clinics.

METHODS

Members of the National Society of Genetic Counselors completed a web-administered survey in February 2008.

RESULTS

Response rate was 36%; the final data analysis included 312 respondents. Eighty-three percent of respondents had two or fewer inquiries about direct-to-consumer genetic testing, and 14% had received requests for test interpretation or discussion. Respondents believed that genetic counselors have a professional obligation to be knowledgeable about direct-to-consumer genetic testing (55%) and interpret results (48%). Fifty-one percent of respondents thought genetic testing should be limited to a clinical setting; 56% agreed direct-to-consumer genetic testing is acceptable if genetic counseling is provided. More than 70% of respondents would definitely or possibly consider direct-to-consumer testing for patients who (1) have concerns about genetic discrimination, (2) want anonymous testing, or (3) have geographic constraints.

CONCLUSIONS

Results indicate that genetic counselors have limited patient experiences with direct-to-consumer genetic testing and are cautiously considering if and under what circumstances this approach should be used.

Pre-counseling education for low literacy women at risk of Hereditary Breast and Ovarian Cancer (HBOC): patient experiences using the Cancer Risk Education Intervention Tool (CREdIT)

The Cancer Risk Education Intervention Tool (CREdIT) is a computer-based (non-interactive) slide presentation designed to educate low-literacy, and ethnically and racially diverse public hospital patients at risk of Hereditary Breast and Ovarian Cancer (HBOC) about genetics. To qualitatively evaluate participants’ experience with and perceptions of a genetic education program as an adjunct to genetic counseling, we conducted direct observations of the intervention, semi-structured in person interviews with 11 women who viewed CREdIT, and post-counseling questionnaires with the two participating genetic counselors. Five themes emerged from the analysis of interviews: (1) genetic counseling and testing for breast/ovarian cancer was a new concept; (2) CREdIT’s story format was particularly appealing; (3) changes in participants’ perceived risk for breast cancer varied; (4) some misunderstandings about individual risk and heredity persisted after CREdIT and counseling; (5) the context for viewing CREdIT shaped responses to the presentation. Observations demonstrated ways to make the information provided in CREdIT and by genetic counselors more consistent. In a post-session counselor questionnaire, counselors’ rating of the patient’s preparedness before the session was significantly higher for patients who viewed CREdIT prior to their appointments than for other patients. This novel educational tool fills a gap in HBOC education by tailoring information to women of lower literacy and diverse ethnic/racial backgrounds. The tool was well received by interview participants and counselors alike. Further study is needed to examine the varied effects of CREdIT on risk perception. In addition, the implementation of CREdIT in diverse clinical settings and the cultural adaptation of CREdIT to specific populations reflect important areas for future work.

"I know what you told me, but this is what I think:" perceived risk of Alzheimer disease among individuals who accurately recall their genetics-based risk estimate

PURPOSE

This study evaluates the Alzheimer disease risk perceptions of individuals who accurately recall their genetics-based Alzheimer disease risk assessment.

METHODS

Two hundred forty-six unaffected first-degree relatives of patients with Alzheimer disease were enrolled in a multisite randomized controlled trial examining the effects of communicating APOE genotype and lifetime Alzheimer disease risk information.

RESULTS

Among the 158 participants who accurately recalled their Alzheimer disease risk assessment 6 weeks after risk disclosure, 75 (47.5%) believed their Alzheimer disease risk was more than 5% points different from the Alzheimer disease risk estimate they were given. Within this subgroup, 69.3% believed that their Alzheimer disease risk was higher than what they were told (discordant high), whereas 30.7% believed that their Alzheimer disease risk was lower (discordant low). Participants with a higher baseline risk perception were more likely to have a discordant-high risk perception (P < 0.05). Participants in the discordant-low group were more likely to be APOE epsilon4 positive (P < 0.05) and to score higher on an Alzheimer disease controllability scale (P < 0.05).

CONCLUSION

Our results indicate that even among individuals who accurately recall their Alzheimer disease risk assessment, many people do not take communicated risk estimates at face value. Further exploration of this clinically relevant response to risk information is warranted.

Explaining Mendelian inheritance in genetic consultations: an IPR study of counselor and counselee experiences

The explanation of Mendelian inheritance is a key component of most genetic counselling consultations, yet no evidence base exists for this area of practice. This qualitative study used Interpersonal Process Recall (IPR) to explore how information about X-linked inheritance is provided and received in genetic counseling. Twelve consultations involving two senior genetic counselors and 21 counselees were videotaped. Section(s) of videotape featuring the explanation were subsequently played back separately to both counselees and counselors and their responses and reflections recorded. All interviews were fully transcribed and analysed using the constant comparison method. A personalized diagram, drawn "live" by the counselor during the consultation was recalled by counselees as being central to their understanding of the "bottom line". This helped bridge the gap between scientific information and their family experience and did not appear to require a baseline understanding of genetic concepts such as genes or chromosomes. Counselors reflected on the diagram's positive impact on the way they sequenced, paced and tailored the explanation. A positive counselor-counselee relationship was vital even during this educative exchange: for counselees to feel at ease discussing complex genetic information and to help gauge counselee understanding.

Perceptions of high-risk care and barriers to care among women at risk for hereditary breast and ovarian cancer following genetic counseling in the community setting

Data are limited regarding barriers to care among women, with or at risk for hereditary breast and ovarian cancer (HBOC), following genetic counseling in the community setting. Using a telephone survey, we retrospectively addressed perceptions of post-genetic counseling medical care and barriers to care among 69 at-risk women from the non-academic setting. Of these, all agreed that following cancer screening recommendations was better than not following them; none felt recommendations were too difficult to follow; all believed screening would help keep them healthy; 57% believed screening would prevent cancer. Twenty-five percent noted discomfort with breast imaging; 29% found ovarian cancer screening uncomfortable. Close to a quarter of participants reported difficulty deciding whether or not to undergo risk-reducing mastectomy while 10% noted difficulty deciding for or against bilateral salpingo-oophorectomy. There were no perceived major barriers to care, although 38% felt that screening reminders would be helpful, and 10% needed more help in following through with care. Overall, participants believed that they were benefiting from their post-genetic counseling medical care. This work identified HBOC-related support needs to include: informational resources that promote improved understanding of cancer risk and high-risk management; screening reminder systems; and decision support tools.

Patient satisfaction with cancer genetic counseling: a psychometric analysis of the Genetic Counseling Satisfaction Scale

Satisfaction is an important patient reported outcome of genetic counseling, as it is one of the elements used by professional organizations and healthcare accrediting bodies to determine the quality of professional work. However, empirical research on patient satisfaction with genetic counseling has been limited, partly due to the lack of standardized measures available to assess this construct. The purpose of this study was to conduct a psychometric analysis of a new satisfaction measure, the Genetic Counseling Satisfaction Scale (GCSS), within a sample of women participating in a no-cost cancer genetic counseling and testing program. The sample consisted of 61 women undergoing counseling and testing for hereditary breast-ovarian cancer risk (BRCA1/2 testing) who completed the GCSS following pretest counseling. The results suggest that the GCSS was reliable (Cronbach's coefficient alpha = 0.90) and that participants were highly satisfied with the care they received. In addition, there were no differences in satisfaction between cancer genetic counseling and prenatal counseling participants (based on preexisting norms), and satisfaction did not vary by sociodemographic characteristics. Implications and recommendations are discussed.

Interventions to improve patient education regarding multifactorial genetic conditions: a systematic review

The careful education of patients with complex genetic disease is essential. However, healthcare providers often have limited time to spend providing thorough genetic education. Furthermore, the number of healthcare professionals possessing strong genetics training may be inadequate to meet increasing patient demands. Due to such constraints, several interventions have been investigated over the past decade to identify potential resources for the facilitation of this specific type of patient education. This systematic literature review of these interventions for patient education attempts to elucidate the answer to the question: is there sufficient evidence for best practice for delivering genetic information to patients with multifactorial conditions? The various interventions (CD-ROM, group counseling, video/decision aid, and miscellaneous) were analyzed in terms of quality criteria and achievement of specific outcomes and were rated according to the Stetler model for evidence-based practice. Seven main outcomes were evaluated: (1) objective and subjective knowledge assessment, (2) psychological measures (general anxiety, depression, stress, cancer worry), (3) satisfaction/effectiveness of intervention, (4) time spent in counseling (time spent on basic genetic information vs. specific concerns), (5) decision-making/intent to undergo genetic testing, (6) treatment choice and value of that choice, and, finally (7) risk perception. Overall, the computer interventions resulted in more significant findings that were beneficial than any other category followed by the video category, although the group and miscellaneous categories did not measure all of the outcomes reported by the other two categories. Nevertheless, while these groups had neutral or negative findings in some of the outcomes, the computer intervention group showed significant improvement in genetics knowledge, psychological measures, satisfaction/effectiveness, time spent with counselor, and decision/intent to undergo testing.

Evaluation of group genetic counseling for hereditary breast and ovarian cancer

As demand for genetic counseling regarding hereditary cancer continues to grow, more efficient methods of providing this service must be explored. In this pilot study, group genetic counseling was offered to two different cohorts of women seeking genetic counseling for Hereditary Breast and Ovarian Cancer. Seven group sessions, designed to cover all aspects of an individual genetic counseling appointment, were conducted. Although patients were receptive to group genetic counseling, a significant proportion chose individual counseling when given the option. Advantages of group genetic counseling include shared experience and increased efficiency. Disadvantages include increased frustration at not being eligible for genetic testing, group influence on decision-making, privacy concerns, increased need for follow-up, and difficulty booking group appointments. Overall, the level of patient satisfaction with group genetic counseling was similar to that of individual counseling. The results of this pilot study suggest that further research is needed to determine whether group genetic counseling is an acceptable alternative to individual counseling.

Psychosocial consequences of genetic counseling: a population-based follow-up study

We aimed to examine the psychosocial impact of genetic counseling for hereditary breast and ovarian cancer 1 year following genetic counseling. We conducted a population-based prospective follow-up study of 213 women who received genetic counseling for hereditary breast and ovarian cancer, 319 women who underwent mammography (Reference Group I), and a random sample of 1,070 women from the general population (Reference Group II). The prevalence of anxiety decreased by 4.7% (95% CI: -3.5; 12.8) from baseline to 1 year of follow-up in the Genetic Counseling Group. Likewise, it decreased by 2.5% (95% CI: -4.5; 9.5) in Reference Group I and by 1.1% (95% CI: -2.3; 4.7) in Reference Group II. The prevalence of depression increased equally (1-3%) in the three study groups. 52% of the women referred for genetic counseling experienced cancer-specific distress at baseline and this proportion decreased to 41% after 12 months of follow-up. This decrease of 10.8% (95% CI: 1.4; 20.8) exceeded the decrease observed in both Reference Groups. However, it was statistically significant only in the case of Reference Group II (p=0.006). Our findings indicate that genetic counseling can help alleviate cancer-specific distress among women with a family history of breast and ovarian cancer. Further, genetic counseling does not appear to have an adverse impact on general anxiety, symptoms of depression, or health-related quality of life.

A multimedia mobile phone-based youth smoking cessation intervention: findings from content development and piloting studies

BACKGROUND

While most young people who smoke want to quit, few access cessation support services. Mobile phone-based cessation programs are ideal for young people: mobile phones are the most common means of peer communication, and messages can be delivered in an anonymous manner, anywhere, anytime. Following the success of our text messaging smoking cessation program, we developed an innovative multimedia mobile phone smoking cessation intervention.

OBJECTIVE

The aim of the study was to develop and pilot test a youth-oriented multimedia smoking cessation intervention delivered solely by mobile phone.

METHODS

Development included creating content and building the technology platform. Content development was overseen by an expert group who advised on youth development principles, observational learning (from social cognitive theory), effective smoking cessation interventions, and social marketing. Young people participated in three content development phases (consultation via focus groups and an online survey, content pre-testing, and selection of role models). Video and text messages were then developed, incorporating the findings from this research. Information technology systems were established to support the delivery of the multimedia messages by mobile phone. A pilot study using an abbreviated 4-week program of video and text content tested the reliability of the systems and the acceptability of the intervention.

RESULTS

Approximately 180 young people participated in the consultation phase. There was a high priority placed on music for relaxation (75%) and an interest in interacting with others in the program (40% would read messages, 36% would read a blog). Findings from the pre-testing phase (n = 41) included the importance of selecting "real" and "honest" role models with believable stories, and an interest in animations (37%). Of the 15 participants who took part in the pilot study, 13 (87%) were available for follow-up interviews at 4 weeks: 12 participants liked the program or liked it most of the time and found the role model to be believable; 7 liked the role model video messages (5 were unsure); 8 used the extra assistance for cravings; and 9 were happy with two messages per day. Nine participants (60%) stopped smoking during the program. Some technical challenges were encountered during the pilot study.

CONCLUSIONS

A multimedia mobile phone smoking cessation program is technically feasible, and the content developed is appropriate for this medium and is acceptable to our target population. These results have informed the design of a 6-month intervention currently being evaluated for its effectiveness in increasing smoking cessation rates in young people.

Interventions to improve risk communication in clinical genetics: systematic review

OBJECTIVE

Effective risk communication may enable clients to participate effectively in decision-making about their health and health care. A systematic review of existing literature on risk communication in genetics, and its effects on key outcomes for clients, was undertaken.

METHOD

Systematic searching of six electronic databases and data extraction from included studies; narrative synthesis of results.

RESULTS

Twenty-eight studies were included, principally from cancer genetics. Sixteen communication interventions have been evaluated, generally showing improvements in cognitive outcomes for users, such as knowledge, understanding and risk perception, and without adverse effects on anxiety, cancer-related worry and depression. However, often it was the supportive or emotional elements of counselling that provided benefits to users, rather than the informational or educational elements. Similar results were found in 12 further studies of decision aids which also appear to achieve shorter consultations that can focus more on the supportive elements of counselling.

CONCLUSION

For both communication models and decision aids, the supportive or emotional elements of counselling provided more benefits to users than the informational or educational elements.

PRACTICE IMPLICATIONS

Debate is required on how to strike a balance between the medical model, its agenda and perceived requirements to disclose or discuss a range of issues and the sometimes competing goals of addressing users' concerns, needs for support, issues of loss and relationship problems.

The development of audio-visual materials to prepare patients for medical procedures: an oncology application

This paper describes a systematic process for the development of educational audio-visual materials that are designed to prepare patients for potentially threatening procedures. Literature relating to the preparation of patients for potentially threatening medical procedures, psychological theory, theory of diffusion of innovations and patient information was examined. Four key principles were identified as being important: (1) stakeholder consultation, (2) provision of information to prepare patients for the medical procedure, (3) evidence-based content, and (4) promotion of patient confidence. These principles are described along with an example of the development of an audio-visual resource to prepare patients for chemotherapy treatment. Using this example, practical strategies for the application of each of the principles are described. The principles and strategies described may provide a practical, evidence-based guide to the development of other types of patient audio-visual materials.

Interventions before consultations for helping patients address their information needs

BACKGROUND

Patients often do not get the information they require from doctors and nurses. To address this problem, interventions directed at patients to help them gather information in their healthcare consultations have been proposed and tested.

OBJECTIVES

To assess the effects on patients, clinicians and the healthcare system of interventions which are delivered before consultations, and which have been designed to help patients (and/or their representatives) address their information needs within consultations.

SEARCH STRATEGY

We searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library (issue 3 2006); MEDLINE (1966 to September 2006); EMBASE (1980 to September 2006); PsycINFO (1985 to September 2006); and other databases, with no language restriction. We also searched reference lists of articles and related reviews, and handsearched Patient Education and Counseling (1986 to September 2006).

SELECTION CRITERIA

Randomised controlled trials of interventions before consultations designed to encourage question asking and information gathering by the patient.

DATA COLLECTION AND ANALYSIS

Two researchers assessed the search output independently to identify potentially-relevant studies, selected studies for inclusion, and extracted data. We conducted a narrative synthesis of the included trials, and meta-analyses of five outcomes.

MAIN RESULTS

We identified 33 randomised controlled trials, from 6 countries and in a range of settings. A total of 8244 patients was randomised and entered into studies. The most common interventions were question checklists and patient coaching. Most interventions were delivered immediately before the consultations.Commonly-occurring outcomes were: question asking, patient participation, patient anxiety, knowledge, satisfaction and consultation length. A minority of studies showed positive effects for these outcomes. Meta-analyses, however, showed small and statistically significant increases for question asking (standardised mean difference (SMD) 0.27 (95% confidence interval (CI) 0.19 to 0.36)) and patient satisfaction (SMD 0.09 (95% CI 0.03 to 0.16)). There was a notable but not statistically significant decrease in patient anxiety before consultations (weighted mean difference (WMD) -1.56 (95% CI -7.10 to 3.97)). There were small and not statistically significant changes in patient anxiety after consultations (reduced) (SMD -0.08 (95%CI -0.22 to 0.06)), patient knowledge (reduced) (SMD -0.34 (95% CI -0.94 to 0.25)), and consultation length (increased) (SMD 0.10 (95% CI -0.05 to 0.25)). Further analyses showed that both coaching and written materials produced similar effects on question asking but that coaching produced a smaller increase in consultation length and a larger increase in patient satisfaction. Interventions immediately before consultations led to a small and statistically significant increase in consultation length, whereas those implemented some time before the consultation had no effect. Both interventions immediately before the consultation and those some time before it led to small increases in patient satisfaction, but this was only statistically significant for those immediately before the consultation. There appear to be no clear benefits from clinician training in addition to patient interventions, although the evidence is limited.

AUTHORS' CONCLUSIONS

Interventions before consultations designed to help patients address their information needs within consultations produce limited benefits to patients. Further research could explore whether the quality of questions is increased, whether anxiety before consultations is reduced, the effects on other outcomes and the impact of training and the timing of interventions. More studies need to consider the timing of interventions and possibly the type of training provided to clinicians.

Cancer genetic risk assessment for individuals at risk of familial breast cancer

BACKGROUND

The recognition of an inherited component to breast cancer has led to an increase in demand for information, reassurance, and genetic testing, resulting in the creation of genetics clinics for familial cancer. The first step for patients referred to a cancer genetic clinic is a risk assessment.

OBJECTIVES

To evaluate the impact of cancer genetic risk assessment services on patients at risk of familial breast cancer.

SEARCH STRATEGY

The specialised register maintained by the Cochrane Breast Cancer Group was searched. We also searched MEDLINE, EMBASE, CINAHL, PsycLIT, CENTRAL, DARE, ASSIA, Web of Science, SIGLE and LILACS. The searches covered the period 1985 to February 2005. We also hand-searched relevant journals.

SELECTION CRITERIA

Trials looking at interventions for cancer genetic risk assessment delivery for familial breast cancer were considered for inclusion. Trials assessed outcomes such as understanding of risk, satisfaction and psychological well-being. Studies were excluded if they concerned cancers other than breast cancer or if participants were not at risk of breast cancer. Trials concerning the provision of information or education were also excluded as it was intended to review these separately. Participants could be individuals of any age or gender, with or without a known BRCA mutation, but without a previous history of breast cancer or any other serious illness.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed trial quality and extracted data. Additional information was sought from investigators as necessary. Due to the heterogeneity of both the interventions and outcomes, data were analysed descriptively.

MAIN RESULTS

Fifty-eight papers were identified as relevant to the review, 54 of these were subsequently excluded. The three included trials (pertaining to five papers), provide data on 1251 participants and assessed the impact of cancer genetic risk assessment on outcomes including perceived risk, and psychological distress. This review suggests that cancer genetic risk assessment services help to reduce distress, improve the accuracy of the perceived risk of, and increase knowledge about, breast cancer and genetics. The health professional delivering the risk assessment does not appear to have a significant impact on these outcomes.

AUTHORS' CONCLUSIONS

This review found favourable outcomes for patients' risk assessment for familial breast cancer. However, there were too few papers to make any significant conclusions about how best to deliver cancer genetic risk assessment services. Further research is needed assessing the best means of delivering cancer risk assessment, by different health professionals, in different ways and in alternative locations.

Recall of disclosed apolipoprotein E genotype and lifetime risk estimate for Alzheimer's disease: the REVEAL Study

PURPOSE

To determine whether individuals recall their apolipoprotein E genotype and numeric lifetime risk estimates after undergoing a risk assessment for Alzheimer's disease.

METHODS

One-hundred and four participants underwent Alzheimer's disease risk assessment that included disclosure of apolipoprotein E genotype and a numeric lifetime risk estimate.

RESULTS

At six weeks and one year post-disclosure, 59% and 48% of participants, respectively, recalled their lifetime risk estimate, and 69% and 63% recalled their apolipoprotein E genotype. Participants were more likely to remember their genotype than numeric lifetime risk estimate at one year (P < 0.05). Apolipoprotein E epsilon4-positive participants had better recall of their genotype at both time points (P < 0.05). Participants were more likely to recall whether they carried the "risk-enhancing form of apolipoprotein E" than their specific genotype (P < 0.05).

CONCLUSIONS

These data suggest that apolipoprotein E genotype, especially the presence of an epsilon4 allele, is more memorable than a numeric risk estimate for Alzheimer's disease. Participants recalled genotype information in a more simplified, binary form. Health professionals testing for complex disorders such as Alzheimer's disease must find an appropriate balance between communicating risk in an understandable format and addressing the probabilistic nature of the information.
